My fuel pump was not engaging during start up. 12v all the way to relay (30contact), 6.3v relay(87contact) and 5.2v at pump . I powered the pump directly from the battery and it works. The relay is also good, I took the same jumper I use from the pump to the battery and put it behind the relay at (87contact) and pump worked find. My question is, is it ok to bypass the fuel pump prime connector(use for factory scans) and the electronic engine control module? Both of these devices are after the relay on the same wire pk/bk leading to the pump.
have the same problem?
